Formula:
The electrostatic force (F) between two point charges (q1, q2) separated by a distance (r) is given by Coulomb's Law:
F = k * |q1 * q2| / r2
- F = Electrostatic Force (Newtons, N)
- k = Coulomb's Constant ≈ 8.9875 × 109 N·m2/C2 (in vacuum/air)
- q1 = Magnitude of the first charge (Coulombs, C)
- q2 = Magnitude of the second charge (Coulombs, C)
- r = Distance between the two charges (meters, m)
